Heart Rate Zones for a 68-Year-Old
For a 68-year-old, the Tanaka formula estimates a maximum heart rate of about 160 bpm. That puts your Zone 2 (easy aerobic) at roughly 96–112 bpm and your Zone 4 (threshold) at 128–144 bpm. Below you will find the full 5-zone table, a formula comparison, and a calculator that personalises the numbers if you enter your resting HR.
HRmax ≈ 160 bpm. Your five training zones:
- Zone 1 · Recovery — 80–96 bpm
- Zone 2 · Endurance — 96–112 bpm
- Zone 3 · Aerobic — 112–128 bpm
- Zone 4 · Threshold — 128–144 bpm
- Zone 5 · Maximum — 144–160 bpm

Formula Comparison at Age 68
No single equation is authoritative. The spread below shows why picking a formula matters — the difference between Fox and Nes at your age can move your Zone 2 ceiling by several beats.
| Formula | HRmax at age 68 | Best fit for |
|---|---|---|
| Fox (220 − age) | 152 | Casual reference |
| Tanaka | 160 | Adults 40+ |
| Gellish | 159 | Active adults |
| Nes / HUNT | 167 | Trained endurance |
| Gulati | 146 | Women |

Frequently Asked Questions
What is the maximum heart rate for a 68-year-old?
Using the Tanaka formula (208 − 0.7 × age), the estimated maximum heart rate for a 68-year-old is about 160 bpm. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 150 and 170 bpm.
What is Zone 2 heart rate for a 68-year-old?
Zone 2 for a 68-year-old is approximately 96–112 bpm, which corresponds to 60–70% of an estimated HRmax of 160 bpm. You should be able to hold a full conversation at this intensity.
What is the threshold (Zone 4) heart rate for a 68-year-old?
Zone 4 (lactate threshold) for a 68-year-old is roughly 128–144 bpm — 80–90% of HRmax. At this intensity you can only speak in short phrases.
How can I personalise these zones?
Enter your resting heart rate into the calculator to apply the Karvonen method, which anchors zones to your heart rate reserve. This is significantly more accurate than %HRmax alone, especially if you are trained or untrained.
